I offer a bespoke service I usually shoot in 16:9 horizontal format for widescreen tv but but can shoot vertical 9:16 for other meada  if requested. I need to know this before the wedding.
Your personal wishes are very important to me together with your personal wishes about who to include on the video.
I will need the time and place of the wedding and who is conducting the wedding so I can visit and check beforehand. And also the couples names how it will appear on the video titles. The video usually delivered with in 2 weeks of the wedding on a usb memory stick. I typically use 3 cameras with different type of lens to get  different perspective on the proceedings. With variety of microphones for clear sound.
